Was on phendimetrazine 35mg. I took low dosage (dose was 4 of 35mg a day) only used 1. I don't want to take an extended release because the dosage is 105 mg, too high for me, but if I don't take the pill, the gnawing feeling I have in my stomach is overwhelming, even when I have eaten a huge full meal. Dr. Oz said it was grelin. Can this be eliminated without taking phendimetrazine? I need help!
